To all whom 'it may concern:

Bc it known that I, LEE B. P-Uncnu., captain, United States Marine Corps, and a c1t1- will be simple in construction, eiicient in action, and` more certain in operation than tho'se that have heretofore been proposed.

With thesepand other objects 1n view the invention consists in the novel details of coni struction and combinations of parts, more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification, in which like numerals designate like artsv in allthe views AFigure 1 is a side e evational view of a fire arm made in accordance with my invention; Fig. 2 is a longitudinal sectional detail view taken on the hne 2-2 of Fig.- 7, looking in the direction of thev magazme; Fig. 3 is a cross sectional view taken on thel line 3- -3 of Fig. 7, looking in the direction of the arrows; Fig. 4 is a perspective view of the cooking lever; Fin 1s .a sectional detail .view taken on the looking in the direction of the arrows; Fig. 6. is a perspective view of a portion of the operating rod and` its block attachment to the breech bolt; Fig. 7 is an enlar ed side elevational view similar to Fig. 1, ut showing.

Fig. 21 is a cross sectional view taken throng? the receiver at the line 3-3 of Fig. 7 loo in toward the muzzle of the gun, the breech .bo t and feed rollers being omitted and a modified form of cartridge holder being illustrated; and Fig. 22 is a view similar to Fig. 21 showing the cartridge holder in an-` other position.

l 1 indicates any suitable barrel, 2 any suitable stock and 3 any suitable passage from the barrel'adapted to conduct the gases of explosion therefrom: The said passage 3 is inqlosed in a member 4 surroundin the barrel and provided with an enlarged c amber 5 provided with a nip 1e 6 adapted to om the passage 3. Also leading from the passage 3 is a passage 7 adapted to cause gases to impinge` against the shoulder or other member 8 carried by the tube 9 telescoping over the tube 10 attached to a portion of the receiver 11. Surroundingthe rear end of ,the tube 9 is a collar 12 and slidably mounted on said tube. is the hand operated grip member 13, provided ateach end withl the supporting members 130 through which pass the operating rods 30, all as will be more fully disclosed below.

Attached to the collar 12 is an operating rodlff, attached at its rear end to a block 15 having a pin 16 enterin a cam groove 19 he .said block-15 slides backward and forward inthe slot 20 of the receiver. I prefer to inclose the rear portion of the barrel by a casing 22 of wood or other insulating material in order to prevent burning the hands of the operator.

A spring 23 is inclosed by the tubes 9 and 10 in order to return the parts. y Y l As best shown in Figs. 2, 3,A 7 and 8 the receiver is provided on each side with' the through the bolt 18 and the tube 82 located on the inside of said bolt 18 and surrounding the enlargement 60 ofthe firing pin. It

.therefore follows that as the said pm 16 is drawn to the rear through themovement of the rod` 14 and block 15, the said tube 82 will be carried to the rearthus forcing the hammer 63 and ar notch 66 to the rear,

until the saidV notch is engaged by the end 67 a of the scar, and the piece thus cocked.l

0n the other hand when the cooking lever 81 is forced to the rear by hand the hammer through its extension 65 isdirectly brought to the rear until the sear engages the said notch 66: The said hammer is hollow .as shown so that the extreme-end of the' firing pin 58 enters the same, and so that its spring 59 may readily retract the said in within the face of the bolt as illustrated 1n iigsxy 12 and 13 when thepiece is cocked.

1t will now be clear from what has been so far disclosed that by operating the grip 13 the breech may be opened and cartridges inserted one at a time through the opening 86 in the receiver, and the arm thus used as a single loader.

When usin the arm as a single loader it is desirable t at the rollers 31 be not operated, and to this end l provide a means for throwing out of engagement the clutch mem. bers 38 and39: now to be described. The clutch member 38, as best shown in lFig. 20 is provided with a splined member 88 adapted to ht a groove 89 in the extreme rear end of the .operating rod-30, and the said operating rod 30 lis provided with the pin 90 adapted to iit a hole 91 in the extreme end of an extension 92 of the said spline 88.I The said lextreme end 92 of the said spline is further provided with a groove V'93 into which ts a thumb lever 94 illustrated in Figs. 1, 2, 7 and 8.. ltv results from the construction thus discloed 4that upon moving the said lever 94 toward the muzzle the clutch member 38 will slidel on its corresponding operating rod 30 until its teeth are disengaged from the teeth of thecorrespending clutch member 39, so that the saidoperating rod 30 maybe turned without op? erating said clutch member 39 and roller 31.

When itis desired to use' the gun as a vmagazine loader l may provide any suitable form of magazine or ot er1- means for `holding the cartridges, butf I prefer the mechanismeillustrated in Frgs. 3 and 17 and now to be described. l v

I preferably take two pieces of fabric,

Abetween the members 32 and -33 andsecure `the parts together as by stitching at 96. I

ends 105, and 106 ofthe fabric which may be suitably finished oif in the form of metal orr leather pieces or of other material, as may be desired. I prefer that the extreme end shall be finished od in metal and curved as shown so that when the cartridges are resented in position they will readily pass etween the serrated rollers 28 and 31, as best illustrated in Fig. 3. That is to say, the brackets 25 and 26 of the receiver 11 are provided with curved surfaces 108 and 109 over which the extensions 110 of the said metal pieces 105 f I and 106 mayY take, and thereby facilitate the bringing ofthe cartridges up into the proper position 'for feeding the folds of the fabric between the rollers 28 and 31. y

rlhe said pieces of fabric or clip members 32 and 33 having been positioned between said rollers the movement of the action bar 14, or of the grip piece 13 to the rear will cause the driving rollers 31 to support the said members 32 and 33 and to rip the seam as at 104, thus freeing the cartridge 101 while at the same time forcing the said cartridge u101 from its full line position shown in Fig. 3 up through the slot 111 in the receiver and into the dotted line position .indicated in said Fig. 3. The Vsaid slot 111 is provided with 'two extensions or lands 112 against which the body4 of the cartridge takes and thereby prevent the said cartridge from moving upward any farther. The upfiring position, it picks up the cartridge which has been freed from the clip members and 33 and forces the same into tbe breech in the usual manner. When the tiring takes place, the cartridge shell is extracted in the usual manner, it is ejecd by an ejector not shown, while the driving rollers 31 further separate the ufabric clip members 32 and 33, ripping the next seam 103 and bringing another cartridge into place, and the above operation is repeated as long as. there are cartridges to be etl. When all of the cartridges are exhausted the fabric or clip members may be removed from the piece by ripping the seam 190,

y which will occur when the last cartridge such as 32and33 which' may beof any has been red.

Any convenient number of cartridges 'may be heldin the fabric clip and whereas `I 'have shown. only six in' Fig. 17, it is perfectly feasiblertof use ten, twelve or more.

In fact if the gun is to be used as a gas operated gun long sltrips of cartridges may be used or employed and supported in any convenient manner near the gun, so that` the piece would becomean automatic gas` operated gun. l I regard the particular means of putting i up and holding my cartridges as an imloader, to a magazine loader of three, six,

v 26 l secure by any suitable means a box 120v .of belts, in cartridge boxes or al ten or more ,cartridges or can even be changed into an automatic gas operated *gun firing as many cartridges as is supplied by my flexible holders.

In addition to -the above my Said iexible holders or vclips` illustrated in Fig. 17 are' yapplicable to any style of ammunition.

1x1 the' modified form of cartridge feed' illustrated in Figs. 21 and 22, have illustrated a box or cosing for holding my iiexib'le clips in position when a large number of cartridges isto be'employed. That is to say in Fig. 21, between the brackets 25 and ningd to a companion boxlike member 121 as at 122- and `also provided with the hinge 123. Between the two members 120 and 121 may be folded my liexible cartridge clip carrying say said clip may be led out between the rollers ten cartridges and the folds 32 and 33 ofthe 28 and 31 as illustrated in Fig. 3, whereupon the said folds will be ripped apart andL the cartridges fed tothe breech as has bee disclosed above in connection with Fig. 3. On the other hand, `as best' illustrated in Fig. 22 .'When it is desired to use the gun with a larger number of cartridges in my flexible clip the member 120 maybe folded back into the position shown in Fig. 22- and out of the way so that a'ibelt of cartridges or a clip containing anydesired number of cartridges may be fed up directly to` the gun and the same operatedy by the gases of explosion or by hand as may be desired.

Whether the gun is hand operated or gas operated it is desirableto take iup or prbv idefor sti-etching or any inequalities' in the fabric orfolds32 and 33.' To this end I have provided the spring 4:0 as a'connection between the clutch members 39 and the ratchet 41 asabove disclosed, and in order to still insure'ithat thefeed shall properly take place in case the power requiredl is more than will be -transmitted by the spring lhave provided on the interior 'of the rollers 31 the lugs'l25 and on theexterlor of the amarre clutch members 39the lugs '126 which move in the grooves 127 on the interior ofthe said rollers 31. It results from the construction thus disclosed that whenever the relative movement between the clutch member .39 and the rod 30 is'more than will be taken care of by the spring 40 that the lugs 126 will travel .in the grooves 127 and take against the lugs 125, so that the rollers 31 will be positively driven from the rods 30.

The o eration of m improved re arm will be c ear from the oregoin but may beY bri'ey summarized as follows: he fire arm may be used as asin' le loader in which case thebreech is opene grip 13 to the rear,l thus causing the operatl ing rod 14 through the pin 16 and grooves v19 to Irotate the bolt 18 on its axis thus un-l '.locking the same and moving the said bolt,

tothe rear. Cartridges one 'at a time may be then inserted throu the o ening 86 in the' receiver and the bo twill automatically returned by the spring 23. The ieee at the same time is cocked by means o the. in 16 passing through'the tube 82 carried 1n the hollow of the bolt 18, and which tube im-` pinges( against the hammer 63 and carries the same to the rearfuntil the sear notch 66 is caught by' the end 67 of the sear 68. The piedey may also be cocked by hand by simply moving the cockin lever 81 'to the rear in by moving the handV which case the bo y 80 of said lever slidesv in the slot 79 with which the extension 78 -of the receiver 11 is provided. Said cooking lever also enables one to holdv the hammer back after the Sear is released and to let the hammer move forward and thus relieve the tension of the ring`sping% when it is desired to do so.

When itis desired to'use the arm as a magazine loader any suitable magazine may be provided, but itis preferred to employ the form of dexible cartridge clips illustrated in Fig. 17. Theseclips are made byl placing two pieces of a suitable fabric together, sewing the saine between the car-` tridges, leading the bights 32 and 33 between the ripping rollers 31 which rollers are v turned in opposite directions by means of the operating rods 30 as the hand grip moves to the rear and which, rollers accordingly rip the seams between 'the cartridges one at. a

time, while at the same time causing the cartridges to be fed up' one at a time against the lands 112, Fig. 3and into the-,path ofthe bolt, 18. .The bolt 18. according picks up the cartridges one at a time and orces them into the breech .Foi-the gun. These dexible' clips constitute an improved feature of the inventionand they may be made: to hold anyy desired number of 'cartridges so that they are notlimited to a fxed' number a's has ,been the case with metal clips.

When it is desired to use the' gun as an automatic *gas operated gun, gas maybe admitted through the passage 3 into the passage 7, and the abutment 8 and its associated parts blown back after each shot in a manner well known. But when the arm is not to be used as a gas operated gun, in the manner above disclosed, a cock such asc 175 (Fig. 9) may be turned to close olf the entrance of gas into the passage 7.

When using the .arm however 'as a gas operated gun, a larger number of cartridges will be carried to the gun through the chps shown in Fig. 17 and in order to support said larger number of cartridges it isconvenient to provide boxes' such as 120 and 121 into whiohthe flexible clips may be folded, and the cartridges are fed one at a time from these clips in the manner above disclosed. n the still further modified form of`construction shown in Fig. 22 the boxes 120 and 121 are relatively folded as illustrated and a complete belt .of cartridges or a clip containing a still larger number of cartridges may be employed.

When it is desired to use the n. as a single loader it is convenient to isengage the clutch members 38 and 39 so that the feed rollers 31 will not be rotated and `to this end the hand operated levers. 94 are provided f in order to push the clutch member 38 out of engagement with the clutch member 39, whereupon the said members 38 will rotate idly inside the rollers 3l, and the latter will not be rotated.

lt is obvious that those skilled in the art ai; may vary the details of construction, as Well as the arrangementof parts without departing from the spirit' of my invention and therefore I do not wish to be limited to the l above disclosure except as may be 'required 4o by the claims.
